you probably have it at the wrong place.
Run a fake smtp session with
"exim -d+expand+acl -bh some.external.ip.address"
to see what rejects the mail.
But looking at your original post, you could remove this stanza and just
modify your dnsbl stanza like this:
# check for blacklists
deny
!sender_domains = /path/to/whitelist
dnslists = relays.ordb.org : sbl-xbl.spamhaus.org : ...
message = $sender_host_address is listed in ${dnslist_domain}:\
$dnslist_text
